解决8.0.30+使用cahcing_sha2_password时Fastauth报错问题
环境描述: MYSQL服务端版本：8.0.36 Canal:1.1.8 背景：MYSQL服务端版本为8.0.36时采用caching_sha2_password插件认证，使用caching_sha2_password登录插件账号FullAuth登录后服务端存在缓存，再次登录报错。断点发现非首次连接存在包未读的情况，导致后续访问越界。FullAuth情况正常 单元测试： 执行了com/alibaba/otter/canal/parse/driver/mysql/MysqlConnectorTest.java
报错如下：
